Abstract
The stepless speed variator consists of mainly one non-magentic wheel mounted onto the input shaft, one magnetic wheel mounted onto the output shaft and one magnetic wheel and one non-magnetic wheel mounted onto middle shaft with movable axis position. It transmits motion and driving force via magnetic force between the magnetic wheel and the non-magnetic wheel and the position change of the middle shaft to change the applied point of the magnetic force, change transmission ratio and realize stepless speed variation.
Description
The invention belongs to technical field of traffic transportation.
Hyundai Motor requires all to equip speed changer for adapting to travel; These speed changers generally all have fixing gear, are referred to as step change transmission.But,, the work of motor and automobile running perfectly are joined together because the gear number is limited; Optimal speed changer should be the stepless speed variator that can obtain any velocity ratio.For this reason, people have developed variable v-belt drive; And, require height not promoted but make in some vehicles application.
The objective of the invention is: provide a kind of simple in structure, do not have novel stepless speed variator---the magnetic force stepless transmission of wearing and tearing during work.
Its mainly construct by: two magnet-wheels are (by annular permanent magnnet, sleeve, outer dish, telophragma is formed, outer dish, telophragma is made with permeability magnetic material, the thickness at wheel rim place is thick than other position, sleeve is made with non-magnet material, magnet is set in the sleeve, telophragma is fixed on the sleeve, outer dish is positioned at the two ends of magnet and sleeve, outer dish is associated in by tenon with sleeve), two non-magnet-wheels are (by wheel disc, spacer ring is formed, wheel disc is made with permeability magnetic material, spacer ring is made with non-magnet material), input shaft (being loaded on the casing) by bearing, output shaft (being loaded on the casing) by bearing, jack shaft (be contained in movably on the bearing support by bearing, bearing support is controlled its position by joining plate by oil hydraulic cylinder).
Working principle: when jack shaft was in a certain position, the non-magnet-wheel that input shaft rotate to drive on it rotated, the magnet-wheel magnet magnetic line of force on the jack shaft coils through it outside, non-magnet-wheel wheel disc, telophragma, non-magnet-wheel wheel disc, outside coil and get back to magnet; Outside magnet-wheel, coil, telophragma wheel rim place magnetic gap is little, and non-magnet-wheel wheel disc between produce very big magnetic force, drive magnet-wheel by this power and rotate, this moment, velocity ratio was the ratio of magnetic force point of resultant force to two-wheeled centre distance.The transmission principle of magnet-wheel is identical therewith on the non-magnet-wheel of jack shaft and the output shaft; The speed changer resultant gear ratio is that two pairs of wheel velocity ratios are long-pending.When needs change velocity ratio, only need to pass through the joining plate moving shaft holder with oil hydraulic cylinder, can change the jack shaft position, and change the magnetic force point of resultant force on the non-magnet-wheel, and then change velocity ratio.
Accompanying drawing is a structural drawing of the present invention, (1) jack shaft, (2) magnet, (3) sleeve, (4) input shaft, (5) spacer ring, (6) wheel disc, (7) telophragma, (8) outer dish, (9) casing, (10) output shaft, (11) piston, (12) cylinder body, (13) joining plate, (14) movable axle bearing, (15) nut among the figure.
Three axles among the present invention are all made with non-magnet material; For adapting to various torque engines, can add a pair of overdrive gear and increase the magnet-wheel telophragma and the number of non-magnet-wheel wheel disc at input shaft end.
